METHOD FOR TREATING TERRY CLOTH OR PILE FABRICS. I

Application filed October 7, 1925." Serial No. 61,036.

This invention relates to a new and im proved method for treating terry or pile fabrics to produce an upstanding pile or nap thereon.

Objects of the invention are to provide treatment for terry cloth or pile fabrics so that the pile assumes anupstanding posi- Other objects of the invention will be manifest from the detailed description and clainii'appended hereto. 'One practical embodiment of the invention is illustrated in the accompanying drawing forming a part of the specification in which,

The figure is a diagrammatic showing of the various steps involved in the treatment of the cloth according to my invention.

As illustrated the numerals 1 and 2 designate a pair of engaging mangle or wringer rolls mounted on shafts 3 and 4 respectively rotatable in opposite directions and imparting a corresponding rotating movement to said rolls. The numerals 5 and 6 designate a pair of brushes, rotatable on the shafts 7 and 8 respectively, said shafts being adapted to rotate in opposite directions. Terry cloth or other fabric 9, having apile or nap is adapted to be fed to the rolls 1 and 2, whereupon the said cloth leavesthe rolls at a speed corresponding to the speed of said rolls. The cloth after leaving the rolls 1 and 2- is conveyed between the brushes 5 and 6 at the speed imparted to it by said rolls, suitable yielding take up means (not shown) being provided to maintain the cloth taut. Preferably the brushes 3 have a rotating speed somewhat faster than the speed of the rolls 1.

The operation of the device is as follows: The cloth or fabric 5 after being thoroughly washed preparatory to drying and shipment is run through the wringer rolls '1 and 2 where part of the water therein is expelled. The cloth is then usually allowed to dry before being bolted and shipped. I11 the case of pile cloth, which is commonly used for Turkish towelling, the pressure of the rolls compresses the cloth and flattens the pile in a manner to make the cloth appear inferior in quality. By conveying the cloth between i the brushes as above described, subsequent to the passage through the wringer rolls, with the brushes moving in a direction opposite the lay of the flattened pile the pile is picked up by the bristles of the brushes, due

to the fact that the'speed of the brushes is faster than the speed of the clothso that a full, uniform and upstanding pile is produced. The cloth is then allowed to dry, whereby the condition of the cloth after leaving the brushes is rendered relatively permanent.

It frequently happens that cloth or fabrics adapted to have a'rich and uniform pile or nap come from the 100m withthe pile unevenly and imperfectly formed. To straighten out and untangle the pile or nap of the cloth has heretofore been too laboriousan operation to render it feasible so that the cloth is disposed of as an inferior product at a great loss. By conveying such cloth be 1 tween the rotating brushes above described, the pile is straightened and untangled with little labor and with such facility that large quantities of cloth considered inferior in quality are rendered salable.

I claim: y

The method of treating terry cloth, suitable for toweling or the like, which com-- prises passing the cloth in a dampened condition between oppositely rotating rolls, whereby excess moisture is removed and the pile upon either side isgiven a lay in a direction opposite to the movement of the cloth, then passing the cloth between rotating brushes the portions of which, that contact with the surface of the cloth, are m0v-
